Arrow Indy-Race Aluminium Dark Slip-On Silencer Yamaha YZF-R1/M RN32 2015-2016 71829AKN

The Arrow Indy-Race 71829AKN is the product of decades of Italian exhaust craft distilled into a single, purposeful silencer. Finished in Arrow's distinctive dark-anodised aluminium with a carbon end-cap, this slip-on carries the unmistakable Indy-Race aesthetic — race-bred lineage worn openly on the flanks of the Yamaha YZF-R1 and YZF-R1M (RN32, 2015-2016).

Key Features

• Dark-anodised aluminium canister paired with a carbon end-cap for a sinister, race-inspired look that sets this silencer apart from polished or titanium siblings.
• Weighs just 1.93 kg — a meaningful reduction over the factory unit, contributing to improved power-to-weight balance and sharper throttle response.
• Stainless steel internal components resist the sustained heat cycles of both road and track use, ensuring long-term structural integrity.
• Supplied with a DB-killer insert for legal road use, removable for open-class track sessions.
• E-number homologation included — street-legal straight from the box without the need for additional paperwork.
• Designed to pair directly with an Arrow header to form a complete exhaust system for maximum performance gains; works equally well on the standard header.

Design, Finish and Heritage

Arrow has been supplying MotoGP and WorldSBK teams since the 1970s, and the Indy-Race line translates that competition knowledge into a road-legal product. The Aluminium Dark finish is not a paint or coating applied over bare metal — the dark anodising is integral to the aluminium itself, meaning it will not flake, chip or fade with heat. The contrast between the matte-dark body and the woven carbon fibre end-cap is deliberate: it mirrors the colour palette of contemporary race machinery and suits the aggressive lines of the RN32-generation R1/R1M without visual compromise.

Performance and Build Quality

At 250 mm in length, with an inlet diameter of 55 mm and an outlet diameter of 58 mm, the Indy-Race canister is dimensioned to maintain correct exhaust gas velocity for the crossplane-crank R1 engine's firing order. The result is improved throttle response across the mid-range and a more linear power delivery compared to the heavier OEM unit. Arrow recommends a dedicated ECU remap to extract the full performance potential of this silencer — while it is functional on the stock map, a custom mapping will unlock the complete benefit of the freer-flowing exhaust path.

Fitment and Compatibility

This silencer is engineered specifically for the Yamaha YZF-R1 and YZF-R1M, chassis code RN32, covering model years 2015 and 2016. It mounts directly to the original mid-pipe using the standard connection points — no additional brackets or adapters are required for the solo slip-on fitment. For a full-system upgrade, the 71829AKN is compatible with Arrow's own headers for the RN32 platform, creating a complete Arrow exhaust from collector to tip.
